Colibri and Partner Commence Diamond Drilling at Pilar Gold: Unlocking Value in Sonora

Colibri Resource Corporation (TSXV: CBI) and its partner Tocvan Ventures Corp. (CSE: TOC) have kicked off a diamond core drilling program at the Pilar Gold & Silver Project in Sonora, Mexico. This strategic move aims to validate the project's mineral potential, enhance the geological model, and pave the way for a maiden resource estimate. The program, set to drill up to 1,250 meters, will focus on the Main Zone target, with the potential to expand to adjacent trends.



The Pilar project, located in the Caborca Gold Belt of northwestern Sonora, has demonstrated significant potential with historical drilling results, including:

* 116.9 meters of 1.2 grams per tonne gold, including 10.2 meters of 12 g/t Au and 23 g/t silver;
* 108.9 meters of 0.8 g/t Au, including 9.4 meters of 7.6 g/t Au and 5 g/t Ag;
* 63.4 meters of 0.6 g/t Au and 11 g/t Ag, including 29.9 meters of 0.9 g/t Au and 18 g/t Ag;

These results, coupled with encouraging metallurgical test work and a planned test mine/bulk sample program in Q3 2025, highlight the project's potential as a modest low-cost gold producing asset.



The diamond drilling program is expected to provide valuable data, enhancing the geological model and supporting a maiden resource estimate for the Pilar Main Zone and adjacent trends. This estimate will be a critical milestone in the project's advancement, showcasing its mineral potential and economic viability.

In addition to the drilling program, Colibri and Tocvan are advancing plans for a test mine/bulk sample of up to 50,000 tonnes of material in Q3 2025. This program will generate important economic parameters, demonstrating the project's potential as a near-term producer and attracting further investment and partnerships.



The partners are currently reviewing several proposals for non-dilutive methods to fully finance the test mine, which could help preserve shareholder value by minimizing dilution.

In conclusion, the commencement of the diamond drilling program at the Pilar Gold & Silver Project marks a significant step in Colibri and Tocvan's strategy to unlock value in Sonora. With a well-defined resource and a successful test mine, the project could attract further investment and development, ultimately enhancing shareholder value. Investors should closely monitor the progress of this strategic initiative as it unfolds.
